| Abstract: | Two types of typical co-injection moulding technologies including bi-color injection molding and sandwich injection molding are discussed.Gas-assisted co-injection moulding technology and lamellar injection moulding technology based on traditional co-injection moulding are also presented,and the process,advantage and application of each of the four co-injection molding technologies are introduced.The effect of process parameters on bi-color injection molding is discussed,and the breakthrough of core melt front phenomenon together with its influencing factors is also discussed. |
